Cut Loop Pile Fabric with Composite Yarn for Enhanced Dust Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mops made from microfiber fabrics with cut loop pile face reduced cleaning efficiency due to degraded sliding properties and inability to effectively catch minute dust particles or human hairs, as the elastic repulsion and restoring force are compromised.
Innovation Solution
A manufacturing method involving a synthetic multifilament yarn as a core yarn, combined with a splittable microfiber yarn as a covering yarn, where the core yarn is heat-treated to protrude outwardly at the cut loop sections, enhancing polishing and sliding properties by creating a hook-like structure that effectively catches foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If microfiber fabrics with cut loop pile are used to increase water absorption and cleaning effect, then water absorption power increases, but sliding properties and elastic restoring force are degraded
Solution Approach 1:
The invention uses a composite yarn structure combining synthetic multifilament core yarn with microfiber covering yarn. The synthetic core provides elastic restoring force and sliding properties, while the microfiber covering provides water absorption. This composite structure resolves the contradiction by integrating materials with complementary properties.
Solution Approach 2:
The invention applies different properties to different parts of the yarn: the core yarn has high elasticity and smooth surface for sliding, while the covering yarn has high water absorption. This local differentiation of material properties allows the fabric to simultaneously achieve good sliding properties and water absorption.
2Ease of manufacture
If microfiber yarns are used to improve polishing properties, then polishing properties increase in initial cleaning stage, but elastic repulsion is decreased
Solution Approach 1:
The composite yarn structure combines microfiber covering yarn for polishing with synthetic core yarn for elastic repulsion. The microfiber surface provides polishing action while the elastic core restores the loop pile after compression, resolving the contradiction between polishing and elastic repulsion.
3Ease of operation
If synthetic multifilament yarn is used as core yarn to improve sliding properties, then sliding properties improve, but ability to catch minute dust particles and human hairs is reduced
Solution Approach 1:
The invention combines synthetic multifilament core yarn for sliding properties with microfiber covering yarn for catching foreign substances. The smooth synthetic core enables sliding while the microfiber covering with its fine structure traps dust particles and hairs, resolving the contradiction.
Solution Approach 2:
Different parts of the yarn perform different functions: the synthetic core provides sliding capability while the microfiber covering provides foreign substance catching. This functional differentiation resolves the contradiction between sliding and catching abilities.
4Stability of the object's composition
If covering yarn is tightly fixed to core yarn through heat treatment to improve structure stability, then structural integrity improves, but outwardly protruding shape of core yarn at cut sections is reduced
Solution Approach 1:
The invention optimizes heat treatment parameters (temperature, time) to achieve partial fixation rather than complete bonding. This allows the core yarn to maintain both structural integrity through some fixation and outward protruding shape through controlled insufficient fixation, resolving the contradiction.

AI summary
The present invention provides fabrics with cut loop pile comprising a core yarn of a synthetic multifilament yarn and covering yarn of a split microfiber yarn and a manufacturing method thereof. The core yarn at the section where said loops are cut is outwardly protruded from the covering yarn, wherein the synthetic multifilament core yarn has been separated into multiple filaments to function as hooks. The fabrics with cut loop pile show superior characteristics in polishing properties, sliding properties, water absorption properties, rapid drying properties and feeling of touch since polishing can be performed while easily catching foreign substances such as extremely minute dust particles or human hairs and the like by the hook-shaped multifilaments of the core yarn. Thus the fabrics with cut loop pile according to the present invention can be used usefully in products such as various kind of mats, towels, bathroom products, and the like including dishcloths and mops.
