Circular Knit Single Jersey Interlock

Soft Knit Mattress Fabric

Product Description

Soft knit mattress fabric is produced on circular knitting machines using either single jersey or interlock construction methods. Unlike woven fabrics that use perpendicular warp and weft interlacing, knit structures are formed by interlocking loops of yarn in a continuous spiral or reciprocating motion. This loop-based architecture imparts inherent elasticity in both length and width directions, with elongation capacity ranging from 30% to 80% depending on yarn type and stitch density. The fabric conforms to mattress contours without requiring separate elastic trim or gathering tapes. Typical yarn inputs include combed cotton, polyester-cotton blends, modal, or TENCEL Lyocell, with stitch densities from 18 to 28 needles per inch. The resulting surface has a textured hand feel and drapes over foam or fiber cores with minimal tension-induced distortion.

Construction Parameters

Machine Type Circular knitting · 30-34 inch diameter
Gauge Range 18GG – 28GG
Stitch Type Single jersey / Interlock / Rib
Fabric Weight 140 gsm – 320 gsm
Course Density 40-60 courses per cm
Wale Density 28-42 wales per cm

Core Advantages

A
Omnidirectional Stretch Knit loop architecture provides 35-70% elongation in both machine and cross-machine directions, accommodating foam compression without seam stress.
B
Breathable Open Structure Inter-yarn voids in knit construction maintain air permeability values of 200-450 mm/s, reducing moisture accumulation at the sleep surface.
C
Seamless Body Sizing Circular knit tubes can be produced in widths matching mattress dimensions (90-200 cm), eliminating side seams that cause pressure points.
D
Recovery Resilience After 50,000 compression cycles (ASTM D3574), knit fabrics recover to 92-96% of original thickness without permanent set.

Application Areas

Foam Mattress Covers
Stretch-fit encasements for memory foam and polyurethane foam cores requiring conformal fit.
Mattress Topper Casings
Removable covers for gel-infused and ventilated topper layers.
Pillow Shells
Knit pillow covers with four-way stretch for down alternative and shredded foam fill.
Adjustable Bed Bases
Flexible covers for articulated bed frames where woven fabrics restrict joint movement.

Performance Metrics

Bursting Strength≥ 350 kPa (Mullen burst test)
Air Permeability180 – 420 cm³/cm²/s (FX 3300)
Moisture Wicking Rate5-12 mm per 30 sec (vertical strip test)
Dimensional Change≤ 3.5% after 3 wash cycles at 40°C
Pilling ResistanceGrade 3.5-4 (Martindale 2000 cycles)
Colorfastness (Wash)Grade 4 (AATCC 61-2A)

Processing Considerations

Edge curling during cutting
Single jersey knit has inherent curl at cut edges. Solution: Apply fusible knit tape (10-15 mm width) or use interlock construction which has balanced face/back loop structure.
Stitch distortion after washing
Pre-treatment with open-width relaxing conveyor (120°C, 8 m/min) stabilizes loop geometry; shrinkage reduced from 8% to ≤3%.
Snagging during mattress assembly
Compact yarns with twist multiplier ≥ 4.2 produce denser surface loops less prone to mechanical snagging.

Maintenance Specifications

Washing 40°C machine wash, gentle cycle. Load capacity ≤ 75% of drum volume to prevent loop distortion.
Detergent Liquid neutral detergents (pH 5.5-7.0). Avoid fabric softeners which deposit films between loops.
Drying Low heat (≤60°C) tumble dry or flat dry. Hanging causes lengthwise stretching.
Storage Flat roll storage on core tubes. Avoid folding or stacking under weight which creates permanent crease marks.
GRS Certified (on rPET variants)
OEKO-TEX Class I/II
Flammability compliant (BS 7175 / CA TB 117)

Product Range & Application Engineering

Soft knit mattress fabric

Hangzhou Xiaoshan RongLi Clothing Co., Ltd. is a Soft knit mattress fabric manufacturer serving industrial projects that require a defined process window, reliable integration and a documented technical scope.

Our approach connects the product configuration with the workpiece, production target, quality requirement and automation plan. The resulting scope covers the main equipment, line interfaces, acceptance basis and lifecycle support needed for a coordinated installation.

Configured Around the Application

We define the configuration around the required operation, material grade, workpiece dimensions, processing sequence, tolerance and output per shift. Product variety and changeover frequency are also incorporated because they affect capacity margin, tooling, controls, access and automation level.

Our technical proposal states the sizing assumptions and normal operating range instead of relying only on a theoretical maximum. Drawings, representative samples and process-trial data allow the product and tooling arrangement to be aligned before configuration approval.

Technical Scope and Configuration

The technical scope can cover rated capacity, working range, stroke or travel, speed, usable work area, clearance, accuracy, repeatability, rigidity, drive and control architecture, power requirements and compatible tooling. We distinguish rated values, adjustable ranges and configuration-dependent performance in the proposal.

  • Performance is matched to the intended working point, not only to a headline maximum.
  • Our scope identifies included equipment, optional equipment and site-supplied interfaces.
  • Drawings, layout data and utility requirements support project planning.
  • Control language, data interfaces, recipes, traceability and line communication are defined for the application.

Automation, Safety and Site Integration

The base machine or product is one part of the complete installation. Our integration scope can account for feeding, transfer, tooling, guarding, sensors, conveyors, lubrication, scrap handling, inspection and connected equipment, with physical interfaces, signals and commissioning responsibilities defined in an interface document.

Safety provisions are aligned with the destination market and plant requirements. The documented scope identifies guards, interlocks, emergency-stop circuits, risk-reduction features and conformity documents applicable to the delivered configuration.

Quality Control and Acceptance

Our project scope connects critical-component selection, fabrication, assembly, inspection and pre-shipment testing with the agreed specifications. Factory acceptance conditions can define the test material, operating duration, measurement method and records supplied with the equipment.

Relevant factory resources, quality records, technical drawings and change-control documents provide a practical basis for technical review. Certification references are applied only when their issuer, scope and validity match the delivered configuration.

Application and Project Matrix

Project Area Application Information Our Technical Output
Application fit Material, part drawing, process and output target Sizing calculation and recommended configuration
Acceptance Measured tolerances, test duration and sample Inspection plan and FAT record
Lifecycle support Shift pattern, maintenance resources and destination Service scope, manuals and spare-parts plan

Total Cost, Delivery and Lifecycle Support

Our proposal can separate the base product, tooling, options, auxiliary equipment, packaging, delivery documents, installation, commissioning, training and initial spare parts. It also defines delivery terms, production milestones, approval points and the effect of approved changes on price or lead time.

Lifecycle support considers energy use, consumables, lubrication, wear parts, maintenance access, diagnostics, software and spare-parts availability. Maintenance intervals, recommended spares, warranty boundaries and available remote or on-site support can be documented for the destination country.

Information We Use to Configure Your Solution

  • Part drawing, material specification, dimensions and tolerance requirements
  • Process sequence, tooling information and representative samples
  • Target cycle rate, shifts per day, annual volume and planned capacity margin
  • Required configuration, automation level and line interfaces
  • Destination voltage, frequency, utilities, floor space and environmental conditions
  • Safety, documentation, certification and language requirements
  • Inspection method and factory/site acceptance criteria
  • Packaging, delivery terms, installation, training and service expectations
  • Requested spare-parts package, warranty terms and quotation validity
